I have gone through the videos and gitrepo which are suggested here
I clone this directory in my local drive, as you can see below

Now I follow the steps which are described here
1) rooted my cmd to the project dir
which is E:\Temo\ngForce-master
2) now I run "npm install".
3) After that I also run "npm install grunt-cli -g"
4) Now I run grunt deploy.
till now everything is working fine. it asked me for
Username, password, and security token.
but I am getting below error in my console
please suggest me some way to integrate ngForce using grunt. I have gone through many places but nothing helps me for this issue. I will be grateful to you.
Thanks in advance.
